2.5A12-EX Rejuvenated Battery Sat in Subfreezing temps for months – started right up!

The Tesla Chargers 2.5A12-EX battery is still being planned for release soon.

Here is a short video I took of my 1977 Datsun 620 pickup that sat for months in subfreezing temperatures.

The battery was already around 7+ years old and was dead before the 2.5A12-EX rejuvenated it.

That rejuvenated battery sat in these temps all this time and started this truck right up with full cranking ability. That would be hard for even some new batteries in these conditions but it was not a problem for the old rejuvenated battery.
